Spectrophotometric Population Synthesis of Early Type Galaxies

We have developed a new stellar population synthesis model for calculating colours and absorption line indices in early type galaxies. This model can work either for single-age stellar populations or in an evo...

Evidence for leading spiral arm formation in NGC 7479

Azimuthal profiles of the spiral NGC 7479 in theB andI passbands have been analyzed using a subset of the azimuthal parameters proposed by Beckman and Cepa (1989), to look for the presence of shock fronts in the ...

A photometric study of the double ring structure of NGC 4736

In this study we present photometric results for the galaxy NGC 4736: infrared and visible profiles. After a careful correction for the extinction within the galaxy based on measured neutral gas surface densit...
